Multimedia & Battery Life Performance
In this segment, the LG Optimus 2X impresses but also fails in certain areas. To kickstart, its 4.0-inch LCD screen is excellent, displaying true blacks, rich and vivid colors. It isn't a stretch to say that the visual experience is almost parallel to the one on the Samsung's patented Super AMOLED screens, boasting of good readability under bright sunlight. Hence, flipping through photos or playing games can be very satisfactory on the smartphone. Messaging is a fluid affair too, not only in terms of agility but also thanks to the decently sized 4.0-inch screen, which gave us ample space for our fingers to maneuver. Those aside, an acceptable 480 x 800 pixels resolution is sufficient for comfortable video playback.
Surfing on the smartphone yielded no problems; generally, the user experience was smooth and receptive on its 4.0-inch touchscreen. Throughout our duration of handling the phone, it never lagged or crashed once. We attribute the smoothness and lag-free experience to the built-in Tegra 2 processor. Audio is average, boasting of airy and weak vocals with strong bass. The media player comes with equalizer choices that range from virtual surround, bass boost, XtraBass to classical - you can choose to switch the sound effects entirely or stick with one of these presets.
As with most high-end smartphones, the Optimus 2X is equipped with a front facing 1.3-megapixel camera and a rear 8-megapixel camera with flash. We conducted our usual imaging tests to check on its photographic performance, concentrating on the main camera on the back.
On the resolution chart, both the horizontal and vertical LPH showed readings of 1300 and 1000, results which are pretty high for a mobile phone. However, colors were somewhat washed-out but otherwise, relatively accurate. In our test shot, we noticed aggressive compression artifacts along the edges of the objects pictured, which could be a result of the built-in noise reduction software. Nonetheless, the overall photographic performance is rather lackluster, with even the 5-megapixel Nexus S triumphing in terms of performance.
As usual, we compare the Optimus 2X's battery performance with a selected group of devices chosen based on their similarities across battery capacities, display sizes, resolution and processing power. This standard battery test consists of looping a 240 x 320 pixels resolution video clip at 100% volume and screen brightness, with Wi-Fi and Bluetooth active with push email or data being pulled at regular intervals. For the LG Optimus 2X, we compared it against similar Android devices such as the Google Nexus S, Samsung Galaxy S and the Google Nexus One.

The LG Optimus 2X underperformed in this area, displaying the weakest result of the bunch, only lasting for a fair 5+ hours when we ran our tests. Judging by the power consumption benchmark results, the phone uses about 28-30% more power compared to the rest. Factors like screen sizes, UI and differing operating systems play a part in optimizing battery consumption - and so does the processor. In this case, despite having a more powerful processor, the phone's battery life in intensive usage takes a 50-100 minutes cut - chalking up to a less-than-efficient power consumption. Notably, while rationing it for normal day-to-day operations, the phone could last for at least three-quarters of a full day.
